Description

Technical Field

[0001] The invention relates to the technical field of tire detection, and in particular to a rubber tire wear resistance detection device. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are usually installed on metal rims. They can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the vehicle's driving performance. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

[0003] The inner wall of a solid rubber tire is relatively smooth. During the wear resistance test experiment, a fixed device is required to clamp the inner wall of the solid tire. If the tire rotates too fast and the inner wall of the tire is relatively smooth, the tire may slip out of the outer surface of the clamping device due to centrifugal force. Therefore, the present invention designs a rubber tire wear resistance test device for solid rubber tires to solve the above problem. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a rubber tire wear resistance testing device, which specifically comprises: an inner cylinder, the inner wall of which is slidably connected to an outer plate, the inner wall of which is fixedly connected to an inner plate, and the inner wall of which is provided with a groove;

[0005] The rubber tire wear resistance testing equipment also includes:

[0006] A telescopic rod, wherein the output end of the telescopic rod is fixedly connected with a friction block, a support seat is arranged below the friction block, and the upper surface of the support seat is fixedly connected with the bottom of the inner tube, a clamping mechanism is fixedly connected to the inner wall of the support seat, a scraping mechanism is arranged below the clamping mechanism, and the upper surface of the scraping mechanism is fixedly connected with the lower surface of the inner plate. There are two protrusions on the outer surface of the outer plate that can slide with the grooves provided on the inner wall of the inner tube, and the outer plate is inserted into the inner tube to achieve clamping and fixing, and the solid rubber tire is placed on the upper surface of the clamping mechanism, and the inner wall of the solid tire is fixed and rotated by the clamping mechanism. When the telescopic rod is started, the friction block can be driven close to the outer surface of the tire, and the friction block plays a role in wear resistance detection during the rotation of the tire. The scraping mechanism can clean the inner wall of the inner tube, and collect and process the rubber debris dropped during the friction between the friction stone and the tire, and the debris can fall into the U-shaped groove at the bottom of the inner wall of the inner tube for centralized collection. When a rubber solid tire needs to be placed in the inner cylinder for wear resistance testing, the outer plate is separated from the inner cylinder to facilitate placement of the tire. After the tire is placed, the outer plate is inserted into the inner wall of the inner cylinder.

[0007] Furthermore, the clamping mechanism comprises:

[0008] A stepper motor, wherein the stepper motor is fixedly connected to the inner wall of the support seat, the output end of the stepper motor is fixedly connected to a rotating shaft, the end of the rotating shaft away from the stepper motor is fixedly connected to a supporting box, and a limiting component is provided on the outer surface of the supporting box;

[0009] The limiting component is fixedly connected to the outer surface of the support box, and the inner wall of the support box is slidably connected with a pressure block, and the pressure block is fixedly connected with an electric rod on the side close to the inner wall of the support box. When the stepper motor is started, it can drive the rotating shaft and then drive the rotation of the support box and the tire. The pressure block is squeezed by the tire, and then the fixed block fixes the inner wall of the tire. During the rotation of the tire, the limiting components on both sides of the tire can prevent the tire from slipping outward due to excessive rotation speed. At the same time, under the emergency braking of the clamping mechanism, the support box stops rotating, and the limiting components will also prevent the tire from sliding outward from the surface of the support box due to continued slipping and rotation. When the tire is placed, the electric rod can be started to push the pressure block to clamp the inner wall of the tire.

[0010] Furthermore, the limiting component includes:

[0011] A limiting shaft is rotatably connected to the inner wall of the supporting box, a compression spring is fixedly connected to the inner wall of the limiting shaft, a slide is fixedly connected to one end of the compression spring away from the limiting shaft, and a protrusion is fixedly connected to one side of the slide away from the compression spring.

The slide plate is slidably connected to the inner wall of the limit box. When the tire needs to be taken away, the slide plate close to the outer plate side is pressed into the limit shaft, and the protrusion can be slid out from the inner wall of the semicircular groove. At this time, the slide plate is pressed to rotate the limit box and the limit shaft downward by 90 degrees until the side of the limit box close to the support box becomes horizontal.

[0013] Furthermore, the cleaning component comprises:

[0014] The scraper is slidably connected to the outer surface of the limit box, the inner wall of the scraper is fixedly connected with a scraper shaft, the end of the scraper shaft close to the limit box is fixedly connected with a motor, the outer surface of the scraper shaft is provided with a thread, and the outer surface of the thread is threadedly connected with a cleaning plate. The motor can drive the scraper shaft and the scraper to rotate, and when the scraper rotates to the other side, the motor drives the scraper shaft and the scraper to reverse, so that the rubber debris on the surface of the limit box can be scraped off, and at the same time, the thread on the surface of the scraper shaft can drive the sliding of the cleaning plate, and the debris falling from the surface of the limit box is scraped off the gap between the limit box and the T-block, so that the debris falls into the inner wall of the inner cylinder.

[0015] Furthermore, the scraping mechanism comprises:

[0016] A servo motor is fixedly connected to the inner wall of the support seat, a bending rod is fixedly connected to the output end of the servo motor, an adjustment component is slidably connected to the upper surface of the bending rod, and an auxiliary component is fixedly connected to the upper surface of the bending rod. The servo motor can drive the rotation of the bending rod and the auxiliary component to scrape off the debris on the inner wall surface of the inner cylinder.

[0017] Furthermore, the adjustment component comprises:

[0018] An arc-shaped plate, the upper surface of the arc-shaped plate is fixedly connected to the lower surface of the inner plate, the inner wall of the arc-shaped plate is provided with a slide groove, the inner wall of the slide groove is slidably connected to an inclined block, the inner wall of the inclined block is rotatably connected to an adjustment shaft, and the outer surface of the adjustment shaft is fixedly connected to an adjustment plate. The upper surface of the bending rod can slide in contact with the lower surface of the arc-shaped plate during rotation, and the lower surface of the bending rod will slide in contact with the inner wall of the inner cylinder. There is an annular gap between the adjustment plate and the arc-shaped plate, and the upper surface of the adjustment plate is also in contact with the lower surface of the inner plate. The adjustment component is symmetrically arranged with respect to the inner cylinder, wherein the lower surfaces of the outer plate and the inner plate are both fixedly connected to the adjustment component.

[0019] Furthermore, the auxiliary components include:

[0020] A fixed frame, the fixed frame is fixedly connected to the upper surface of the bending rod, the inner wall of the fixed frame is slidably connected with a pressing component, the inner wall of the pressing component is fixedly connected with a fixing rod, and the lower surface of the pressing component is fixedly connected with a pressing spring.

[0021] Furthermore, the pressing component comprises:

[0022] A lower pressing plate is slidably connected to the inner wall of the fixed frame, a rubber rod is fixedly connected to the inner wall of the lower pressing plate, an end of the rubber rod away from the lower pressing plate is fixedly connected to an air bag, and an air pipe is fixedly connected to the lower surface of the lower pressing plate. The pressing component can squeeze the gas inside the fixed frame so that the gas enters the cavity opened on the inner wall of the lower pressing plate through the air pipe, pushing the air bag to slide along the inner wall of the lower pressing plate.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) During the wear resistance test of the tire, after the limit component is rotated from a horizontal angle to a vertical angle, the limit box can be locked. The locked limit box can limit the two sides of the tire to prevent the tire from sliding off the upper surface of the support box due to the centrifugal force during high-speed rotation; at the same time, the limit box can further prevent the tire from detaching from the surface of the support box and hitting the inner cylinder, causing damage to the inner cylinder.

[0025] (2) When the tire is placed on the upper surface of the support box, the extension of the electric rod can make the pressure block slide out of the inner wall of the support box and fit tightly to the inner wall of the tire, so that tires with different inner diameters can be fixed, which is universal. At the same time, the fixing effect of the equipment on the tire can avoid the problem that the friction block causes the tire to shake due to the friction between the two during the wear resistance test of the tire, thereby affecting the wear resistance test effect.

[0026] (3) After the clamping mechanism is emergency braked, the tire may slip along the upper surface of the support box after high-speed rotation. During the rotation process, the tire will rub against the outer surface of the limit box, resulting in rubber debris remaining on the surface of the limit box. Through the cooperation of the scraper shaft, scraper and cleaning plate, the surface of the limit box and the debris that falls from the surface of the limit box to the surface of the T-block can be completely cleaned up to avoid debris remaining on the surface of the limit box and affecting the subsequent limiting effect of the limit box on the tire. At the same time, it is prevented that too much debris remains. The next time the tire slips, the debris on the surface of the limit box will rub against the tire, resulting in severe wear on the side of the tire.

[0027] (4) During the wear resistance test between the friction block and the tire, some debris will fall onto the inner wall of the inner cylinder. The U-shaped design of the inner cylinder can facilitate some debris to slide into the groove at the bottom of the inner cylinder. The bending rod pushes some debris into the groove at the bottom of the inner cylinder. When the bending rod rotates to the inner wall on the other side of the inner cylinder, the debris will be pushed upward. When the bending rod is reset, it cannot effectively drive the debris back to the bottom of the inner wall of the inner cylinder. Therefore, through the coordinated design of the arc plate and the adjustment plate, when the bending rod rotates to the high point of the inner wall on the other side of the inner cylinder, the pressing part can slide down and contact the upper surface of the inner wall of the inner cylinder. During the reversal of the bending rod, the debris that cannot be cleaned will be scraped off to the bottom of the inner wall of the inner cylinder, avoiding the problem of incomplete cleaning of the debris on the inner wall of the inner cylinder.

[0028] (5) The airbag in the pressing component contacts the inner wall of the inner tube, and the debris that cannot be cleaned by the bending rod is scraped into the bottom of the inner wall of the inner tube. The airbag in the scraping component can be extended and retracted along the inner wall of the lower pressing plate, and the debris attached to the inner wall of the airbag can be pushed down to avoid the debris remaining on the surface of the airbag and affecting the cleaning effect of the airbag. At the same time, the airbag is made of soft material, and when cleaning the inner wall of the inner tube, it will not have excessive friction with the inner wall of the inner tube, avoiding the problem of friction damage to the inner wall of the inner tube due to the scraping material being too hard.

DETAILED DESCRIPTION

[0041] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0042] For the first embodiment, please refer to Figure 1-Figure 8 The present invention is a rubber tire wear resistance testing device, specifically comprising an inner cylinder 1, the inner wall of the inner cylinder 1 is slidably connected to an outer plate 2, the inner wall of the inner cylinder 1 is fixedly connected to an inner plate 3, and the inner wall of the inner cylinder 1 is provided with a groove 4;

[0043] The rubber tire wear resistance testing equipment also includes:

[0044] A telescopic rod 5, the output end of which is fixedly connected to a friction block 6, a support seat 7 is provided below the friction block 6, and the upper surface of the support seat 7 is fixedly connected to the bottom of the inner tube 1, a clamping mechanism 8 is fixedly connected to the inner wall of the support seat 7, a scraping mechanism 9 is provided below the clamping mechanism 8, and the upper surface of the scraping mechanism 9 is fixedly connected to the lower surface of the inner plate 3. Among them, there are two protrusions on the outer surface of the outer plate 2 that can slide with the grooves 4 opened on the inner wall of the inner tube 1. The outer plate 2 is inserted into the inner wall of the inner tube 1 to achieve clamping and fixing. The solid rubber tire is placed on the upper surface of the clamping mechanism 8. The inner wall of the solid tire is fixed and rotated by the clamping mechanism 8. The telescopic rod 5 is started to drive the friction block 6 close to the outer surface of the tire, which plays a role in wear-resistant detection during the rotation of the tire. The scraping mechanism 9 can clean the inner wall of the inner tube 1 and collect and process the rubber debris dropped during the friction between the friction stone and the tire. The debris can fall into the U-shaped groove at the bottom of the inner wall of the inner tube 1 for centralized collection. When it is necessary to place the rubber solid tire in the inner tube 1 for wear-resistant detection, the outer plate 2 is separated from the inner tube 1 to facilitate the placement of the tire. When the tire is placed, the outer plate 2 is inserted into the inner wall of the inner tube 1.

[0045] The clamping mechanism 8 comprises:

[0046] A stepper motor 81, wherein the stepper motor 81 is fixedly connected to the inner wall of the support seat 7, the output end of the stepper motor 81 is fixedly connected to a rotating shaft 82, and one end of the rotating shaft 82 away from the stepper motor 81 is fixedly connected to a supporting box 83;

[0047] The limiting component 84 is fixedly connected to the outer surface of the supporting box 83 , and a pressing block 85 is slidably connected to the inner wall of the supporting box 83 . The side of the pressing block 85 close to the inner wall of the supporting box 83 is fixedly connected to an electric rod 86 .

[0048] When the stepper motor 81 is started, the rotating shaft 82 can be driven to rotate the support box 83 and the tire. The tire squeezes the pressing block 85, and the fixing block 88 fixes the inner wall of the tire. During the rotation of the tire, the limiting components 84 on both sides of the tire can prevent the tire from slipping outward due to excessive rotation speed. At the same time, when the clamping mechanism 8 is emergency braked, the support box 83 stops rotating, and the limiting components 84 also prevent the tire from sliding outward from the surface of the support box 83 due to continued slipping and rotation. When the tire is placed, the electric rod 86 is started to push the pressing block 85 to clamp the inner wall of the tire.

[0049] When in use, first remove the outer plate 2 from the inner wall of the inner tube 1 to leak out the space of the inner tube 1, so as to facilitate the placement of the rubber tire on the outer surface of the clamping mechanism 8. In the initial state, the side of the limiting component 84 close to the support box 83 is not in a vertical state, but in a horizontal state, which will not hinder the rubber tire from being placed on the upper surface of the support box 83. When the rubber tire is ready to be placed on the upper surface of the support box 83, in the initial state, the electric rod 86 is telescopic, driving the pressure block 85 to telescope into the interior of the support box 83, which will not hinder the placement of the tire. When the tire is placed, the electric rod 86 is started and extended to drive the pressure block 85 to press against the inner wall of the rubber tire. The inner wall of the tire is fixed by three pressure blocks 85. After the tire is fixed, the center of the tire is aligned with the center of the rotating shaft 82.

[0050] After the tire is fixed, the limiting component 84 is rotated to a certain angle so that the limiting component 84 fits against the side surface of the tire. After limiting the left and right sides of the tire, the stepper motor 81 is started to drive the rotation of the rotating shaft 82, which can continue to drive the rotation of the support box 83 and the limiting component 84, and can also drive the tire to rotate inside the inner tube 1. The telescopic rod 5 is started to drive the friction block 6 to approach the tire, and the wear resistance of the tire is tested through the friction block 6.

[0051] The limiting component 84 includes:

[0052] The limiting shaft 841 is rotatably connected to the inner wall of the supporting box 83, the inner wall of the limiting shaft 841 is fixedly connected with a compression spring 842, one end of the compression spring 842 away from the limiting shaft 841 is fixedly connected with a slide plate 843, and the side of the slide plate 843 away from the compression spring 842 is fixedly connected with a protrusion 844.

[0053] The outer surface of the limiting shaft 841 is fixedly connected with a T-block 845, and the side of the T-block 845 away from the support box 83 is fixedly connected with a limiting box 846, and the side of the limiting box 846 close to the T-block 845 is slidably connected with a cleaning component 847. The limiting shaft 841 can rotate with the inner wall of the support box 83, and the side of the support box 83 in contact with the protrusion 844 is provided with a semicircular semicircular groove, which can facilitate the engagement of the protrusion 844. The limiting shaft 841 and the limiting box 846 can be fixed by the cooperation of the semicircular groove provided in the support box 83 and the protrusion 844. The slide plate 843 is slidably connected to the inner wall of the limit box 846. When the tire needs to be removed, the slide plate 843 close to the outer plate 2 is pressed into the limit shaft 841, and the protrusion 844 can slide out from the inner wall of the semicircular groove. At this time, press the slide plate 843, and rotate the limit box 846 and the limit shaft 841 downward by 90 degrees until the side of the limit box 846 close to the support box 83 becomes a horizontal position.

[0054] When in use, after the tire is fixed, the inner wall of the tire is fixed to the upper surface of the support box 83. In the initial state, the side of the limit box 846 close to the support box 83 is in a horizontal state, rather than Figure 6 As shown in the state, the limit box 846, the limit shaft 841 and the T-block 845 are rotated upward from the horizontal direction to 90 degrees around the inner wall of the support box 83 until the side of the limit box 846 close to the support box 83 becomes a vertical state, as shown in FIG. Figure 6 When the limit box 846 rotates, the slide plate 843 and the protrusion 844 inside the limit shaft 841 also rotate accordingly, until the limit box 846 rotates to 90 degrees, and the protrusion 844 enters the inner wall of the semicircular groove opened on the inner wall of the support box 83. Under the elasticity of the compression spring 842, the protrusion 844 and the slide plate 843 will slide to the side away from the compression spring 842 until the protrusion 844 enters the semicircular groove on the inner wall of the support box 83, achieving the clamping effect between the protrusion 844 and the groove. At this time, the limit shaft 841, the T-block 845, and the limit box 846 are completely locked. During the rotation of the tire, both sides of the tire can be limited to protect it, so as to prevent the clamping mechanism 8 from rotating too fast, causing the tire to rotate rapidly and possibly slip outward. During the sliding of the slide plate 843 and the protrusion 844 , the upper surface of the slide plate 843 will also come into sliding contact with the inner wall of the T-block 845 and the limit box 846 , thereby limiting the sliding of the slide plate 843 .

[0055] When the tire needs to be removed, the slide plate 843 close to the side of the support box 83 is pressed into the inside of the limiting shaft 841, and the protrusion 844 can slide out from the inner wall of the semicircular groove. At this time, the slide plate 843 is pressed to rotate the limiting box 846 and the limiting shaft 841 downward 90 degrees. During the rotation process, the protrusion 844 is compressed into the inside of the limiting shaft 841 by the inner wall of the support box 83 until the side of the limiting box 846 close to the support box 83 becomes a horizontal position.

[0056] Cleaning component 847 includes:

[0057] The scraper 8471 is slidably connected to the outer surface of the limit box 846, the inner wall of the scraper 8471 is fixedly connected with a scraper shaft 8472, the end of the scraper shaft 8472 close to the limit box 846 is fixedly connected with a motor 8473, the outer surface of the scraper shaft 8472 is provided with a thread 8474, and the outer surface of the thread 8474 is connected with a cleaning plate 8475. The motor 8473 can drive the scraper shaft 8472 and the scraper plate 8471 to rotate. When the scraper plate 8471 rotates to the other side, the motor 8473 drives the scraper shaft 8472 and the scraper plate 8471 to rotate in the opposite direction, so that the rubber debris on the surface of the limit box 846 can be scraped off. At the same time, the thread 8474 on the surface of the scraper shaft 8472 can drive the sliding of the cleaning plate 8475 to scrape the debris falling from the surface of the limit box 846 to the gap between the limit box 846 and the T-block 845, so that the debris falls into the inner wall of the inner tube 1.

[0058] During use, when the clamping mechanism 8 stops rotating urgently, the tire may continue to rotate at high speed and slip. At this time, both sides of the tire will rub against the outer surface of the limit box 846. Rubber debris generated during the friction process will appear on the outer surface of the limit box 846, and some of the debris will also fall onto the outer surface of the T-block 845.

[0059] When the tire speed stops and the tire is taken off, the motor 8473 starts to drive the rotation of the scraper shaft 8472, and the scraper shaft 8472 can drive the rotation of the scraper plate 8471. The scraper plate 8471 can rotate along the outer surface of the limit box 846 during the rotation, and the debris on the surface of the limit box 846 can be scraped off. At the same time, during the rotation of the scraper shaft 8472, the thread 8474 on the surface of the scraper shaft 8472 can drive the cleaning plate 8475 to slide along the surface of the T-block 845, and the debris can be pushed to the gap between the T-block 845 and the limit box 846, so that it falls into the inner cylinder 1. The cleaning of the debris on the outer surface of the limit box 846 can prevent the limit box 846 from affecting the limiting effect of the tire when limiting the tire. At the same time, when the tire slips and rotates, the attached debris will increase the wear strength of the tire, resulting in increased wear on both sides of the tire.

[0060] For the second embodiment, please refer to Figure 1-Figure 11 The present invention is a rubber tire wear detection device, and the scraping mechanism 9 includes:

[0061] The servo motor 91 is fixedly connected to the inner wall of the support seat 7, the output end of the servo motor 91 is fixedly connected to a bending rod 92, the upper surface of the bending rod 92 is slidably connected to an adjustment component 93, and the upper surface of the bending rod 92 is fixedly connected to an auxiliary component 94. The servo motor 91 can drive the rotation of the bending rod 92 and the auxiliary component 94 to scrape off the debris on the inner wall surface of the inner cylinder 1.

[0062] During use, since the friction block 6 performs wear resistance testing on the tire, a lot of debris will fall onto the inner wall of the inner cylinder 1 during the friction between the friction block 6 and the tire. The servo motor 91 is started to drive the rotation of the bending rod 92. The bending rod 92 can drive the rotation of the auxiliary component 94 during the rotation process, and the debris on the surface of the inner cylinder 1 will be scraped off to the inside of the U-shaped groove at the bottom of the inner wall.

[0063] The adjustment component 93 comprises:

[0064] The arc plate 931 has an upper surface fixedly connected to the lower surface of the inner plate 3, a slide groove 932 is provided on the inner wall of the arc plate 931, a slant block 933 is slidably connected to the inner wall of the slide groove 932, an adjustment shaft 934 is rotatably connected to the inner wall of the slant block 933, and an adjustment plate 935 is fixedly connected to the outer surface of the adjustment shaft 934. The upper surface of the bending rod 92 can slide in contact with the lower surface of the arc plate 931 during rotation, and the lower surface of the bending rod 92 will slide in contact with the inner wall of the inner cylinder 1. There is an annular gap between the adjustment plate 935 and the arc plate 931, and the upper surface of the adjustment plate 935 is also in contact with the lower surface of the inner plate 3. The adjustment component 93 is symmetrically arranged with respect to the inner cylinder 1, wherein the lower surfaces of the outer plate 2 and the inner plate 3 are both fixedly connected with the adjustment component 93.

[0065] When in use, the bending rod 92 will slide along the lower surface of the arc plate 931 and the upper surface of the inner cylinder 1 during the rotation process. When the bending rod 92 slides along the inner wall of the inner cylinder 1, when the bending rod 92 is at a high position, the debris on the inner wall can be scraped off to the inner wall of the U-shaped groove at the bottom of the inner wall of the inner cylinder 1, but when the bending rod 92 rotates to the inner wall on the other side of the inner cylinder 1, the debris on the inner wall on the other side will be driven to the upper surface of the inner cylinder 1. When the bending rod 92 reaches the highest designated position, the servo motor 91 will drive the bending rod 92 to reverse. When the bending rod 92 slides down along the inner wall of the inner cylinder 1, the debris attached to the surface of the bending rod 92 may not slide into the U-shaped groove with the bending rod 92, so there will be debris on the other side of the inner wall of the inner cylinder 1 remaining on the inner wall of the inner cylinder 1, and the bending rod 92 cannot be completely cleaned.

[0066] The auxiliary components 94 include:

[0067] The fixing frame 941 is fixedly connected to the upper surface of the bending rod 92, the inner wall of the fixing frame 941 is slidably connected with a pressing component 942, the inner wall of the pressing component 942 is fixedly connected with a fixing rod 943, and the lower surface of the pressing component 942 is fixedly connected with a pressing spring 944. The pressing component 942 can slide downward along the inner wall of the fixing frame 941 and press the pressing spring 944 at the bottom.

[0068] When in use, the bending rod 92 can drive the rotation of the fixing frame 941, the pressing component 942 and the fixing rod 943 during the rotation. When the fixing rod 943 reaches the top of the bottom of the inner wall of the inner cylinder 1 during the rotation, the lower surface of the fixing rod 943 slides with the upper surface of the arc plate 931. When the fixing rod 943 contacts the inclined block 933, the inclined block 933 is pressed by the slide groove 932. Therefore, the fixing rod 943 can only slide along the upper surface of the inclined block 933 and slide to the upper surface of the adjustment plate 935. When the fixing rod 943 rotates to the upper surface of the adjustment plate 935, it can drive the pressing component 942 to extend upward by a certain distance, that is, the outer surface of the pressing component 942 slides outward along the inner wall of the fixing frame 941 by a certain distance and stretches The downward pressure spring 944 waits until the fixing rod 943 slides along the surface of the adjustment plate 935 to the highest point and breaks away from the contact with the upper surface of the adjustment plate 935, the fixing rod 943 and the pressing component 942 are reset under the pull of the pressing spring 944, and the fixing rod 943 falls to the upper surface of the arc plate 931 again, and the fixing rod 943 will drive the pressing component 942 to slide down, and the pressing component 942 will slide downward along the inner wall of the fixing frame 941 until the lower surface of the pressing component 942 contacts the upper surface of the inner wall of the inner cylinder 1. During the reversal of the bending rod 92, the pressing component 942 will also reverse, and the debris that the bending rod 92 cannot scrape off will be scraped off through the bottom of the pressing component 942. At this time, the debris remaining on the inner wall surface of the inner cylinder 1 will be scraped off by the pressing component 942.

[0069] When the fixing rod 943 is reversed, the fixing rod 943 breaks away from the contact with the upper surface of the adjustment plate 935 and comes to the upper surface of the curved plate 931. In the process of rotating along the upper surface of the curved plate 931, it touches the inclined block 933 and pushes the inclined block 933 to rotate upward around the outer surface of the adjustment shaft 934 by a certain angle, pushing the inclined block 933 away. The inclined block 933 will not affect the rotation of the fixing rod 943. When the fixing rod 943 breaks away from the contact with the inclined block 933, the inclined block 933 is reset around the adjustment shaft 934 under the action of gravity and continues to be stuck on the inner wall of the slide groove 932.

[0070] The pressing component 942 includes:

[0071] The lower pressing plate 9421 is slidably connected to the inner wall of the fixed frame 941, the inner wall of the lower pressing plate 9421 is fixedly connected with a rubber rod 9422, one end of the rubber rod 9422 away from the lower pressing plate 9421 is fixedly connected with an air bag 9423, and the lower surface of the lower pressing plate 9421 is fixedly connected with an air pipe 9424. The lower pressing component 942 can squeeze the gas inside the fixed frame 941, so that the gas enters the cavity opened on the inner wall of the lower pressing plate 9421 through the air pipe 9424, and pushes the air bag 9423 to slide along the inner wall of the lower pressing plate 9421.

[0072] When in use, when the fixing rod 943 detaches from the adjustment plate 935 and falls onto the surface of the arc plate 931, the fixing rod 943 and the lower pressure plate 9421 are reset along the inner wall of the fixing frame 941 under the elasticity of the lower pressure spring 944, and the bottom of the lower pressure plate 9421 touches the inner wall of the inner tube 1. When the lower pressure plate 9421 slides downward along the fixing frame 941, the bottom of the lower pressure plate 9421 can squeeze the gas on the inner wall of the fixing frame 941, and the squeezed gas enters the internal space of the lower pressure plate 9421 through the air pipe 9424, pushing the airbag 9423 to a certain extent, so that the airbag 9423 slides along the inner wall of the lower pressure plate 9421 The airbag 9423 is in contact with the inner wall of the inner cylinder 1, and the debris that cannot be cleaned by the bending rod 92 can be scraped to the inside of the U-shaped groove. The contact between the airbag 9423 and the inner wall of the inner cylinder 1 can avoid the situation where the lower pressure plate 9421 directly contacts the inner wall of the inner cylinder 1 and causes the inner cylinder 1 to be damaged by friction. At the same time, when the fixing rod 943 drives the lower pressure plate 9421 to slide upward along the fixing frame 941, the air pressure on the inner wall of the lower pressure plate 9421 is reduced, and the airbag 9423 is reset under the elasticity of the rubber rod 9422, and the debris that may be attached to the surface can also be scraped off through the sliding friction effect of the inner wall of the lower pressure plate 9421.

[0073] The specific workflow is as follows:

[0074] First, the outer plate 2 is removed from the inner wall of the inner tube 1 to expose the space of the inner tube 1 so as to facilitate the placement of the rubber tire on the outer surface of the clamping mechanism 8 .

[0075] Before the tire is placed, the electric rod 86 drives the pressure block 85 to extend and retract into the inner wall of the support box 83. When the tire is placed on the upper surface of the support box 83, the electric rod 86 extends, which can drive the pressure block 85 to move toward the inner wall of the tire, thereby achieving a clamping effect on the inner wall of the tire.

[0076] After the tire is placed, the limiting component 84 is rotated to a certain angle so that the limiting component 84 fits against the side surface of the tire. After limiting the left and right sides of the tire, the clamping mechanism 8 can drive the tire to rotate after the tire is fixed. The telescopic rod 5 is started to drive the friction block 6 to approach the tire, and the wear resistance of the tire is tested through the friction block 6.

[0077] When the tire needs to be taken out after the inspection is completed, the limiting component 84 is reset and rotated to a proper angle, so that the tire can be taken out from the upper surface of the supporting box 83.

[0078] When cleaning the debris on the inner wall of the inner cylinder 1, the bending rod 92 slides along the inner wall of the inner cylinder 1. When the bending rod 92 is at a high position, the debris on the inner wall can be scraped off to the inner wall of the U-shaped groove at the bottom of the inner wall of the inner cylinder 1. However, when the bending rod 92 rotates to the inner wall on the other side of the inner cylinder 1 and needs to rotate upward along the inner wall of the inner cylinder 1, the debris on the inner wall on the other side will be pushed to the upper surface of the inner wall of the inner cylinder 1. When the bending rod 92 reaches the highest specified position, the servo motor 91 will drive the bending rod 92 to reverse. In the process of the bending rod 92 sliding down along the inner wall of the inner cylinder 1, the debris attached to the surface of the bending rod 92 may not necessarily slide into the U-shaped groove with the bending rod 92.

[0079] When some debris cannot be cleaned up, the bending rod 92 cooperates with the adjusting component 93 so that the auxiliary component 94 can slide down when the bending rod 92 rotates to the highest position of the inner wall of the inner cylinder 1 where it needs to be reset, that is, when the bending rod 92 is out of contact with the adjusting plate 935, the auxiliary component 94 cooperates with the pressing component 942 to scrape the rubber debris on the inner wall of the inner cylinder 1 that cannot be cleaned by the bending rod 92 onto the surface of the U-shaped groove through the extension of the air bag 9423.
